Still waiting on parts for my panel....! Looks like it will take a while before I'm at the same stage (ha ha) as some of you chaps on here. I'm hoping to machine some parts for my meters today, these are going to use little stepper motors so I can get a 270 degree needle swing. I'm also planning on making a somewhat elaborate altitude meter with an embedded 7 segment display and a stepper driven needle. Hopefully this will come together OK, when I have more to display other than just hot air, I'll post some images. I still have a few questions... Although I'm going to be using the Arduino as my main board (actually a ChipKit Max32) I'm planning on running a number of other controls through one of the common USB MAME boards that you can on Ebay, amongst other places. Does anyone have any experience of these? For example, can keyboard actions such as time warp be assigned to buttons connected to one of these things? This is what I'm talking about: http://www.ebay.co.uk/itm/2x-ZERO-DELAY-ARCADE-USB-ENCODER-PC-TO-JOYSTICK-FOR-ARCADE-MAME-FIT-HAPP-PARTS-/261481039277?pt=UK_Video_Games_Coin_Operated_MJ&hash=item3ce17c05ad -CF
